Avoiding catastrophic failure of rock bolts in underground coal mines. This project will examine the factors responsible for the emerging problem of catastrophic failure of rock bolts in underground mines in order to develop strategies for resisting such failures. The consequences of rock bolt failure are potentially enormous from both a mine safety and economic standpoint. The strategies developed are expected to not only reduce the likelihood of injury and death from rock falls but to also red ....Avoiding catastrophic failure of rock bolts in underground coal mines. This project will examine the factors responsible for the emerging problem of catastrophic failure of rock bolts in underground mines in order to develop strategies for resisting such failures. The consequences of rock bolt failure are potentially enormous from both a mine safety and economic standpoint. The strategies developed are expected to not only reduce the likelihood of injury and death from rock falls but to also reduce very expensive mine downtime and avoid costly replacement of broken rock bolts. Australian Rock Bolting Technology is now used internationally and the work will be of substantial significance both nationally and internationally. It will help maintain Australia's international prominence in this field.Read moreRead less

Understanding material behaviour under dynamic loading is essential in dealing with many engineering problems as excavation, fragmentation, earthquake, blasting, and structure design. In geotechnical and structure projects, materials are often subjected to existing confining stresses. The full-field optical techniques, with an ultra-high speed and resolution camera in the system, aims to assist the quantitative measurement of deformation fields including small strain induced in brittle material's failure and identification of constitutive parameters.Read moreRead less

Open pit mine design and production scheduling (OPDPS) deals with the management of cash flows in the order of hundreds of millions of dollars, and is a critical aspect of mining ventures. To enhance decision-making under conditions of uncertainty, this proposal aims to develop a new methodology for OPDPS based on mathematical and statistical techniques which model uncertainty in key parameters, geological, mining and market/cost and their effects on economic forecasts. The new formulation is founded on stochastic integer programming, and its integration with spatial stochastic simulations of geological attributes. Methods developed are computerised and tested in field studies.Read moreRead less

The project aims to provide tools that can identify how mining projects, including associated land use and infrastructure, can play a positive role in sustainable water management. This will be based on new knowledge about mine-land-water relationships, novel approaches to modelling mine site hydrology within regional models and greater emphasis on risk evaluation. This work is essential if resource-rich regions in Australia and beyond are to be developed with sustainability as a goal, and for mining to live comfortably alongside other strategically important water and land users. The main outcome aims to be the development of new tools for predicting and optimising the regional water management opportunities provided by mining.Read moreRead less
Development of a new stochastic short-term production scheduling optimisation approach for open pit metal mines. Stochastic short-term production scheduling (STPS) in open pit mines provides a new framework allowing production schedules to manage risk robustly despite uncertainties in geological and mining conditions. STPS depends on both mining (stockpiling process, multiple ore types and processors, waste production, equipment mobility, feasible sequencing) and geological (in-situ ore variabil ....Development of a new stochastic short-term production scheduling optimisation approach for open pit metal mines. Stochastic short-term production scheduling (STPS) in open pit mines provides a new framework allowing production schedules to manage risk robustly despite uncertainties in geological and mining conditions. STPS depends on both mining (stockpiling process, multiple ore types and processors, waste production, equipment mobility, feasible sequencing) and geological (in-situ ore variability, geological uncertainty, simulated 'future' grade control data) factors. Formulations require development of innovative stochastic goal programming techniques and high-order spatial stochastic simulations. STPS has a major impact on multi-million dollar mining cash flows and affects environmental sustainability. This project represents a strategic priority for some of Australia's largest mining companies.Read moreRead less
